Abstract

본 발명은 컬러 그래픽 처리를 위한 아핀변환 장치에 관한 것으로, 여러 형태의 칼라이미지로 입력되는 영상데이타가 프레임 단위로 전처리부에서 좌표(x,y)및 RGB 색신호로 전환되고, 4×4 부블럭으로 분할된 다음 병렬로 연결된 16개의 AT연산부로 순차적으로 각각 입력되어 16개의 AT연산부에서 동시다발적으로 AT연산되며, 16개의 AT연산으로부터 각각 출력되는 영상데이터가 연산종료부 내의 기설정된 연산종료 조건에 모두 해당되면 종료신호가 16개의 버퍼로 발생되어 16개의 버퍼에 각각 저장된 부블럭의 영상데이터가 최종적으로 출력되므로써, 애니메이션 풍경용 컬러 그래픽 처리를 고속으로 처리할 수 있도록 한 것이다.The present invention relates to an affine converting apparatus for color graphics processing, wherein image data inputted in various types of color images is converted into coordinates (x, y) and RGB color signals in a pre-processing unit on a frame-by-frame basis, and is 4 × 4 subblocks. 16 AT operators are sequentially input to each of the 16 AT operators connected in parallel, and AT operations are simultaneously performed by 16 AT operators. Image data outputted from the 16 AT operations are respectively set in the operation termination unit. If all of the above conditions, the end signal is generated into 16 buffers, and the image data of the sub-blocks stored in the 16 buffers is finally outputted, so that the color graphics processing for the animated landscape can be processed at high speed.
